Applicable conditions
- Acidic or alkaline gases
- Water-soluble odors
- Oil mist, droplets and some dust
- Pretreatment to protect downstream RAO equipment
Core technology
JETA
High-intensity foam scrubbing — Absorption, chemical reaction and capture of oil mist and particles take place in a dynamic foam mass-transfer zone.
Operating limits
The liquid chemistry, materials, stages and dosing must match the pollutants. Poorly soluble, non-reactive, low-concentration VOCs should not rely on scrubbing alone.
System combinations
Install before RAO to control oil mist, particles and water-soluble components, or after RAO to absorb polar oxidation intermediates.
PROCESS & OPERATION
Intensive contact in a dynamic foam zone.
JETA combines counter-current gas–liquid contact, absorption, reaction and capture of some droplets and particles. Single- or two-stage layouts and circulation liquids are configured around the target compounds.

- 01
Gas–liquid contact
Exhaust meets the liquid jet in a turbulent reaction zone.
- 02
Foam mass transfer
Droplet breakup and surface renewal promote contact for absorption and reaction.
- 03
Liquid circulation
Select the liquid chemistry, dosing, make-up water and blowdown strategy.
- 04
Mist separation
Remove entrained droplets before downstream treatment or exhaust discharge.
Liquid management
Select acidic, alkaline or other suitable reaction liquids; track concentration, pH and replacement intervals.
Construction materials
Evaluate PP, FRP or stainless steel against temperature, corrosion and chemical compatibility.
Staging and protection
Use separate stages for mixed compounds and define inlet conditions for downstream equipment.
